(UPDATE 3) Obama's statement to the press (or reading the text off his teleprompters) just started. So far, there is no new information about the explosions that Obama can disclose. "We will get to the bottom of this." And now it's already over. He didn't take any question.
(UPDATE 2) Obama to make a statement to the press at 6:10PM EST.

Feel free to complain to Boston Globe.
NY Post reports the suspect is Saudi, but the article's headline screams "12 dead, 50 more injured", which may or may not be true. But then, area hospitals are treating injured people, and the number looks easily surpassing 50.
There was also an explosion at the JFK Library. Boston Police Commissioner Edward Davis says this is an ongoing event, "“Stay home ... don’t congregate in large crowds."
